CARD-GUIDE FOE TYPE-WRITING MACHINES.

Application filed November 27, 1915.

To all whom it may concern:

Be it known that l. Yum-1n N. Diucw, a

citizen of the l'ni'ted States'of America. residing in Vatertown. in thecounty of Middlesex and State of Massachusetts. have invented certainnew and useful Improvements in Card-Guides for Type-\Vriting Machines,of which the following is a specification.

This invention relates to card guides for typewriting machines and hasfor its object to provide a transparent card and paper guide that willadequately hold cards and paper against the platen in the vicinity ofthe action of the printing devices or type. The invention belongs tothat class of card and paper holders or guides located at thecentral'part of the machine which comprises a guide plate heldstationary relative to the transverse traverse of the carriage with itsupper edge,which may be provided with a scale, adjacent to and justbelow the l ne of print.

Heretofore such guide plates have. been provided with upwardly arrangedguide devices, as fingers, extending across the line of print andlocated adjacent the pointofprint at one or both sides thereof, thearrangement being such that the characters, as printed, are visible andexposed in the printed line for some distance to the left of theprinting point.

It often happens in the use of machines having guides of this characterthat the upper edge or parts of cards, particularly stiff cards, bulgeforward above the scale plate and become marked or smeared by the. inkribbon as it moves in front of the operating type and it is to eliminatethis objectionable feature in the typewriting of cards, without in anyway obstructing the view of the, matter being printed, that thistransparent card guide and guard has been devised.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of that part of a Royal typewritingmachine to which this invention is applied.

of the carriage. The side frames (3 support the rotating platen T andbelow the platen are shown a paper pan 8 and pressure rollers 5) and H).all of usual construction. In Fig. 1 is shown upper glide rollers 11,ribbon vibrator 12 in lower osition and type bar 13 in printingposition.

The eard guide and guard is held stationary relative to the feedingmovements of the carriage and platen, it being secured to the rail 4 ofthe carriage shift frame by means of the guide supports 14 which arefastened at their lower parts to said rail and extend there Fromforwardly and upwardly in front of the laten to a s iort distance belowthe printing line. as indeated in Fig. 3. To the upper ends of the uidesupports 14 is secured. by means of screws or screw studs 15, a guideplate 16 that extends a short distance at each side of the printing:point with its straight upper edge located ]\1Sl; below the line. ofprint. said edge being marked with an indicating scale is shown. Theends of this guide plate are bent ordairved forwardly as shown at 17.

The. parts so far lescribed are similar to corresponding parts atpresent in use on the said Royal machine. The gist or essential featureof this invention is in the construction and applieatioi' of a guide forholding cards, etc... against or toward the platen above the line of priat and for fully protecting or guarding the same from interference byany of the movii g parts of themachine. To accomplish this object. andat the same time leave the vision free to examine the full line ofprinting as the characters are in1- pressed on the can. or paper betweenthe.

guide and platen. said guide 18 is composed of a thin sheet or pi ce oftransparent material which ma v be celluloid or other suitable material.This transparent guide 18 is curved toward the platen. as shown at Fig.3. In the. transparer t guide are forrred holes 19. Fig. 2. which setover the screws or screw studs 1:) of the guide supports whereby it isheld in operative position. This transparent guide is providyd with acentral opening 20 which alines with an opening in the guide platelfi.as shown at Fig. 2, for thepassage of sion. as shown at F5 g. 1.

It will be observed that the guard 18 is of such size that it e: tendsto a considerable extent or esi=i( d the printing point and the type.vhen making an impresthat the two parts of the guide are connected asindicated at 21 above the opening. In this way the guide is made strongand rigid and an unbroken upper edge is provided,

thus avoiding the presenceof points or angles which might 'be engagedby'the cards.

It will also be observed that the guide 18 is' secured to the scaledguide 16 and that when the guide 16 is attached to the rail 4 thetransparent guide which it carries is prop- .erly located. I

I claim: 1. A card guide for typewriting machines comprising a fixedhorizontally arranged plate having its upper edge disposed below theline of print, and a transparent card guide rigidly attached to saidplate having an unbroken upper edge and foruu-d with an opening throughwhich the type pass to the printing point.

2.. A transparent ea rd guide for typewriting machines having aideportions disposed on opposite sides of the printing point, a-

lniddle portion which rigid! connects said side portions, and an openingfor the pas-- sage of the type in combination with means for supportingsaid guide in operative positlon. g
